Are PK/PD important in resistance ?

Just a few of them… 

Pharmacokinetic/ Pharmacodynamics in Drug Development and Evaluation

Pharmacokinetic/ Pharmacodynamics: What are the goals ?

Pharmacokinetic/ Pharmacodynamics

PK/PD and effectiveness: patterns of antimicrobial activity (after WA. Craig, 2000)

PK/PD and effectiveness: patterns of antimicrobial activity (after WA. Craig, 2000)

PK/PD and effectiveness: role of concentration an example with Listeria monocytogenes

PK/PD and FQ effectiveness: in vitro dynamic models

PK/PD of fluoroquinolones and effectiveness in clinics: role of the 24h-AUC / MIC ratio for ciprofloxacin in hospital-acquired pneumonia

Fluoroquinolones: the role of the peak for efficacy: animal models
